Dental X-Ray (OPG)

An OPG (also known as Orthopantomogram) is a type of dental X-ray that provides images of the upper and lower jaw. It’s an essential diagnostic imaging scan for diagnosing dental conditions.

What is a OPG?
An OPG is an X-Ray used in dentistry to provide a view of the upper and lower jaws, including teeth, and surrounding bone structures. This type of X-Ray is a non-invasive imaging technique that is used to view and assess the overall health of the mouth. The images help dentists and orthodontists to diagnose issues, plan treatment and monitor the development of teeth.

A dentist may refer you for an OPG to help them see under the surface of your teeth and gums. There are several reasons why you might need an OPG:

Are there any risks?
OPG imaging procedures are generally safe and commonly used, there are a few considerations and minimal risks associated with them:
- Low Radiation Exposure
  
  Radiation exposure – OPGs only expose patients to a small amount of radiation, the does is generally very low and is considered safe.
  
  Cumulative exposure – Radiation from a single OPG is minimal, repeated exposure can accumulate so it’s important for you to notify your radiology provider of any recent X-rays or imaging studies to avoid any unnecessary radiation exposure.
- Safety Considerations
  
  Pregnancy – While the risk to the unborn is minimal precautions such as using a lead apron is available as a precaution.
  
  Children – Paediatric patients may be provided with protective measures
